PSP Go Cam 300 Vs PSP - 450 Cam? Differences?

Looking into buying one of these cameras, Of course the new PSP 450 Camera is bundled with that Invizimals Game which i've found for around £20 instore, The new one is black of course and more slim and doesnt stick out as much, Theres tons of rumours that the camera is an upgraded version of the old 1.3 Mega Pixel Camera, Apparently on the box it mentions the new Camera to be 2 Mega Pixels, People are noting the Camera is only 640x480 which of course equals 0.3 Mega Pixels, it's also noted in the Manual - playstation.com/man…pdf

People havent been able to make the ResolutionHigher to my knowledge so i'd like to hear from someone who owns this weither it true or not and weither its worth me getting the Original Go Cam 300 (Silver) as a quality camera is more important for my psp any feedback will be appreciated as long as it's not negative to my questions
